BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Hybrid Tea Rose Plant

SPECIFICATION

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing ‘KIKA’ as the seed parent with ‘REMEMBER ME’ as the pollen parent.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

-   -   (a) All other cultivars of which I an aware are:         -   (1) Prickles being absent from any stems.         -   (2) Large yellow flower with light pink shading.         -   (3) Single flower to the stem.         -   (3) Strong fragrance.         -   (4) Very consistent free bloomer.     -   (b) Seed parent: White hybrid tea; cluster of three flower; no         prickles. Pollen parent: Copper, red-orange, yellow hybrid tea;         has prickles.         Asexual reproduction of the new rose cultivar by budding onto         the rootstock ‘Dr. Huey’, as performed at Vasco. Calif., shows         that the afore-mentioned and all other distinctive         characteristics come true to form and are established and         transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with color terminology In accordance with The Royal Horticultural Society Colour Chart (RHSCC). The terminology used in the color description herein refers to plate numbers such as: ‘Yellow Group 16A’ found in Fan 1 of The Royal Horticultural Society Colour Chart.
